DESCRIPTION:The conventional wisdom is that aggressive networking requirem
 ents\, such as high packet rates for small messages and microsecond-scale 
 tail latency\, are best addressed outside the kernel\, in a user-level net
 working stack. We present IX\, a dataplane operating system that provides 
 high I/O performance\, while maintaining the key advantage of strong prote
 ction offered by existing kernels. IX uses hardware virtualization to sepa
 rate management and scheduling functions of the kernel (control plane) fro
 m network processing (dataplane). The dataplane architecture builds upon a
  native\, zero-copy API and optimizes for both bandwidth and latency by de
 dicating hardware threads and networking queues to dataplane instances\, p
 rocessing bounded batches of packets to completion\, and by eliminating co
 herence traffic and multi-core synchronization. We demonstrate that IX out
 performs Linux and state-of-the-art\, user-space network stacks significan
 tly in both throughput and end-to-end latency. Moreover\, IX improves the 
 throughput of a widely deployed\, key-value store by up to 3.6 and reduces
  tail latency by more than 2.\n\nShort Bio: I am a PhD student in the Elec
 trical Engineering Department at Stanford University\, advised by Professo
 r Christos Kozyrakis. Before starting my studies at Stanford\, I earned my
  Bachelor's degree in Engineering Science at the University of Toronto. My
  research interests are in computer architecture and systems. Most recentl
 y\, I have been focusing on disaggregated storage systems and resource man
 agement for large-scale datacentres. This summer\, I am excited to be inte
 rning at Microsoft Research\, working with Eno Thereska and the Systems & 
 Networking group.\n
